CVE-2018-16870: medium-severity, new variant of the Bleichenbacher
attack to perform downgrade attacks against TLS, which may lead to
leakage of sensible data. Backported from 3.15.7.
CVE-2019-13628 (currently assigned-only): potential leak of nonce sizes
when performing ECDSA signing operations. The leak is considered to be
difficult to exploit but it could potentially be used maliciously to
perform a lattice based timing attack. Backported from 4.1.0.

The AX_AM_JOBSERVER macro shipped with m4/ax_am_jobserver.m4 is broken on
plain POSIX shells due to the use of `let`.
Shells lacking `let` will fail to run the generated m4sh code and end up
invoking "make" with "-jyes" as argument, fialing the build.
Since there is no reason in the first place for some random package to
muck with the make job server settings and since we do not want it to
randomly override "-j" either, simply remove references to this defunct
macro to let the build succeed on platforms which not happen to use bash
as default shell.

Use download from github archive corresponding to v3.14.4 tag because
the project's website apparently only offers 3.14.0-stable release
downloads.

This seems to cause a false-positive warning/error
while building `libwebsockets-cyassl`.

```
Hardening is enabled by default in libwolfssl at build-time.
However, the `settings.h` header is exported (along with other headers)
for build (via Build/InstallDev).
This looks like a small bug/issue with wolfssl.

This is to eliminate any ambiguity about the cyassl/wolfssl lib.
The rename happened some time ago (~3+ years).
As time goes by, people will start to forget cyassl and
start to get confused about the wolfSSL vs cyassl thing.
It's a good idea to keep up with the times (moving forward).
